如何将ruby从2.0.0更新到最新的ruby for my book air？我已经尝试了大多数CLI教程并且有一些错误，这些错误也不允许我下载rails。这是我在尝试使用rbenv更新时遇到的错误：

 $ rbenv install 2.3.1

你的意思是红宝石2.3.1？ 2.1.3有警告。

我也建议使用自制软件。

brew install rbenv ruby-build

# Add rbenv to bash so that it loads every time you open a terminal
echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile
source ~/.bash_profile

# Install Ruby
rbenv install 2.3.1
rbenv global 2.3.1
ruby -v
gem install bundler

Answer 2

在我的情况下，安装崩溃了，因为我最近重新安装了Xcode而忘记安装命令工具。

运行后

sudo xcode-select --install

我使用rbenv成功安装了Ruby。

从2.0.0更新ruby
